Operation |
API |
Description |
---|---|---|
Adding an index |
addIndices() |
Adds a specified index to an empty table but skips index data generation. You can use this API to add indexes in batches to a table that contains a large amount of data and use the GlobalTableIndexer tool to build index data. |
addIndicesWithData() |
Adds a specified index to a table that contains data and generates index data for existing table data. You can call this API to generate an index and then generate index data when table data is being stored. This API is not recommended when a data table contains a large amount of data. |
|
Deleting an index |
dropIndices() |
Deletes both index metadata and index data. After deletion, the index cannot be used for scan or filter operations. |
Changing index status |
alterGlobalIndicesUnusable() |
Disables a specified index so that it cannot be used for the scan or filter operation. |
alterGlobalIndicesActive() |
Enables an index specified by the user so that it can be used for the scan or filter operation. |
|
alterGlobalIndicesInactive() |
Disables a specified index and skips index data generation so that it cannot be used for the scan or filter operation. This API is usually used for index data re-building. |
|
Viewing created indexes |
listIndices() |
Lists all indexes in a given table. |
